If you are someone who has any concept of what’s going on in your world today, then you have heard about the recent and very tragic shootings in Paris, France.

The main suspects in the first incident are brothers Cherif Kouachi, 32, and Saïd Kouachi, 34; another suspect is 18-year-old Hamyd Mourad, whom officials later said turned himself in.

The Kouachi brothers allegedly stormed the offices of a French satirical news magazine, called Charlie Hebdo, Jan. 7, killing a total of 12 people in their path of terror. Among those twelve was Officer Ahmed Merabet, who was killed after confronting the Parisian terrorists.

A US official claims to have evidence from a French intelligence agent reporting that Saïd Kouachi traveled to Yemen and met with an Al Qaeda affiliate and spent a few months training in small arms combat and marksmanship.

This incident was not the only thing happening in Paris on this particular week; the next day, a man named Amedy Coulibaly killed a female police officer in Paris.

The next day, on Jan. 9, police cornered the Kouachi brothers at a printing business, and later shot and killed them. A hostage they were holding was set free.

Also that day, Coulibaly held up a grocery market with 19 hostages. He allegedly had ties with the two Charlie Hebdo gunmen. Anti-terrorist forces stormed into the grocery store and killed the gunman., but in the siege, four of the hostages were killed.

At the end of the week of terror, three of the terrorists were dead, but a fourth suspect, Hayat Boumeddiene, the partner of the supermarket gunman, is still on the run.

French officials have suspicion that Boumeddiene may hold the key to knowing whether or not the Kouachi brothers and the supermarket shooter are part of a bigger terrorist group forming in France. Updates on this event can be found on bbc.com
